The documentation is not very clear with respect to the relationship between the encoding / codeset / character set of the database and the ctype of the collation. All that it mentions are the following statements (all found on the [22.3. Character Set Support][1] documentation page):

* > each database's character set must be compatible with the database's LC_CTYPE (character classification) and LC_COLLATE (string sort order) locale settings

* > On Windows, ..., UTF-8 encoding can be used with any locale.

* > **Important:** On most modern operating systems, PostgreSQL can determine which character set is implied by the LC_CTYPE setting, and it will enforce that only the matching database encoding is used. On older systems it is your responsibility to ensure that you use the encoding expected by the locale you have selected. A mistake in this area is likely to lead to strange behavior of locale-dependent operations such as sorting.

There is an implication here that the `LC_CTYPE` value only has rules for the characters in its Character Set. A value of `1252` indicates an Extended ASCII Code Page for [Windows Latin1][2]. All of those characters can be encoded into UTF-8 (you current encoding), but that doesn't necessarily mean that locale-aware functions such as `upper`, `lower`, `initcap`, etc will behave as expected when operating on characters that exist outside of the Code Page. This should be testable by running one of those functions on a character that is not in the Windows Latin1 / Code Page 1252 character set. For example, [Latin Small Letter Nj U+01CC][3]:

nj
==

should capitalize to:

NJ
==

So, _if_ the following;

    SELECT upper('nj'), lower('NJ');

returns:

<!-- language: lang-none -->

    NJ	nj

then it looks very positive that the "1252" `LC_CTYPE` value is not adversely affecting anything. It would still be good to try a `SELECT` with an `ORDER BY` since sorting was mentioned a few times in the documentation as an area that would likely be affected if these values -- encoding and LC_CTYPE -- were in conflict.

---

You cannot change either `LC_COLLATE` or `LC_CTYPE` once a database has been created, so you could try creating a new database to see if you can get the desired settings, regardless of what the installer thinks you should have:

    CREATE DATABASE my_db_name WITH
                ENCODING 'UTF8' 
                LC_COLLATE='English_United States.UTF8'
                LC_CTYPE='English_United States.UTF8'
                TEMPLATE=template0;

You might need to look in the [pg_collation][4] system catalog to see what is available.
